Triangles! :D
Types of Triangles.
In the table attached, the lengths of all sides of ∆ABC are equal Therefore, this triangle is an equilateral triangle ‘Lateral’ refers to the sides of a figure
- A triangle with all three sides equal is called an equilateral triangle.
In ∆PQR, the length of the two sides PQ and PR are equal ∆PQR is called an
isosceles triangle.
- A triangle with two equal sides is called an isosceles triangle.
The lengths of the sides of ∆XYZ are all different Such a triangle is called a scalene triangle.
- A triangle with no two sides equal is called a scalene triangle.
In the figures attached in attachment 2, ∆DEF is an acute angled triangle
- A triangle with all three acute angles is called an acute angled triangle.
∆PQR is a right angled triangle
- A triangle with one right angle is a right angled triangle.
∆LMN is an obtuse angled triangle
- A triangle with one obtuse angle is called an obtuse angled triangle.
Points to Remember :
- The sum of the measures of the three angles of a triangle is 180°.
- The sum of the lengths of any two sides of a triangle is always greater than the length of the third side.
